Hello and welcome to ESPN's live updates for what promises to be an all-action heavyweight clash between Derek Chisora and Deontay Wilder.

Billed as "an icon will fall," both Chisora (36-13, 23 KOs) and Wilder (44-4-1, 43 KOs) will both make their 50th professional ring walks at The O2 in London.

Brit Chisora, 42, has said tonight will be his last before he retires from boxing.

Meanwhile American Wilder told ESPN this week his confidence is "through the roof" as he looks to show he can still come out on top in big fights.

Will it be the Union Jack or the Star-Spangled Banner that emerge victorious in London? Follow the action to find out.
